Procedure

To a solution of 3-chloroaniline (0.060 mL, 0.54 mmol) and triethylamine (0.16 mL, 1.14 mmol) in CH2Cl2 (10 mL) was added 3-(2-morpholin-4-yl-ethyl)-imidazo[1,5-a]pyridine-1-carbonyl chloride hydrochloride (150 mg, 0.45 mmol). The mixture was stirred at ambient temperature for 1 h then washed with sat. aq. NaHCO3 (20 mL). The organic layer was separated and the aqueous layer was extracted with dichloromethane (20 mL). The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was chromatographed on silica to yield the title compound (61 mg, 35%). 1H NMR (DMSO-d6) δ 10.0 (1H), 8.45 (1H), 8.15 (2H), 7.81 (1H), 7.35 (1H), 7.20 (1H), 7.10 (1H), 6.94 (1H), 3.49 (4H), 3.26 (2H), 2.81 (2H), 2.44 (4H); m/z (M+H)=385.18.
